The devastating Thomas Fire recently endured by residents of Santa Barbara County burned away some of the area's natural defenses against mudslides, a threat that has tragically been realized in the area as flooding has led to the evacuation of 20,000 residents and at least 13 deaths, according to CBS News.

The sisters, who grew up in Santa Barbara, shared photos of the devastation on social media on Tuesday, calling for hope and help for the battered area.

"My beautiful hometown of Montecito.... Where my roots were placed, where my mother raised me and my family. Completely under water. I really can't believe it. I am praying and thinking so much for our friends in the hospital and their families that are still missing," Bella wrote. "For our horses, dogs, cats-all animals- that gave us happiness, who are now searching for a dry place to lay their heads.. our elementary school... The freeway to drive to school and where @mini_jk_imbig and I would walk after school.. under water. My heart is broken.... I remember when something similar happened in La Conchita about 12 years ago, so close to us and how much it took to rebuild..."

"I can't imagine how Montecito feels now. I am so sorry," she continued. "As always- Please send websites for donations. I'm ready to help. Thank you to the rescue, fire fighters and security teams in SB for staying strong and your hard work to pull out anybody and anything in sight. My love is with you so deeply SB."

"My beautiful hometown, just after getting through weeks of wildfire, has been hit by a major storm. That “river” is the 101 freeway," Gigi tweeted. "Please keep the families of Santa Barbara in your thoughts and prayers."
